Ride Safe!Be careful! always think like we have no right away, let the car go even if you have to but never cross their road, it is not worth the accident.Also prevent getting flat tire by checking your tires at every stop. Thorns dont have a chance to go in tire all the way at once, but after a while, sitting on your tire, it punctures its way into your tire until it flattens your tire, so always check your tire before you get a flat tire.

invest on some tools, screwdrivers, a few pliers, non digital multi-tester, a few parts, like CDI, Magneto, Throttle handle in advance, trust me they are cheap on ebay, but it is worth your time and money, this guy has bunch of cheap parts...http://stores.ebay.com/pccmotoparts

Flat Tires:I don’t think anyone likes to get a flat tire, but it happens, but wouldn’t be nice to prevent it? yes & no… In most cases little thorn gets into tire first, and it takes a while to puncture its way into tire to flat the tube, so on every stop light check your both tires, if you see any foreign object trying to get into your tire remove it before its too late. Also it helps to keep your tires always in good shape and new, it is much easier to replace the old tire with a new one at home than fixing a flat tire on the road. There are times that it is unpredictable, for example a nail comes out of nowhere just to puncture your tire… yes my friend sometimes it just happens...Read More...NOTE:If you need Spark Plug ASAP, buy J8C From Oreilly or any other auto parts store, but the wrench size is bigger:Oreilly store have them.

anyone trying to modify their motor perform only one mod at a time. After you are happy with the way things are working again, then you can consider modifying something else.

If you do several at once and then can’t get it to work correctly it is much more difficult to determine what went wrong.

If you are new to internal combustion engines or 2 stroke motors then you should probably learn and understand the principals upon which they operate before you dive inside the crankcase.

Cleaning:Though fairly water resistant most motorized bicycles are not designed for continued use in rain or power washing.I find a bucket with a small amount of warm water and a grease cutting dish soap like Dawn and an old towel will clean off the grease and grime in short order and not prevent your bike from starting until it ‘dries out’ from a soaking.

Mechanical Maintenance:Bike builds very so widely it is impossible to cover everything for every build but these basics are true on all direct drive builds. Left side drive chain system and rear wheel.I do not keep exact stats but I can safely say that half of the motorized bicycle failures I see are due to poor motor mount or drive train construction, but even my builds are prone to a loose chain or failing rear wheel.To quick check your bike before a ride check the following:Hold the top bar behind the gas tank with your left hand, and grab the top of the motor by the spark plug with your right hand and try to move it back and forth. If it moves AT ALL do NOT ride until you tighten the 2 front and rear motor nuts. Insure the motor is centered when doing this, just look straight down from over the bike, the spark plug should be in the middle.
